Energy is the capacity to do work. All forces require energy to do work. Machines-an object that makes human effort easier.Gravity is the force that pulls objects toward the Earth. One type of energy can turn into another but can never be destroyed.Some types of energy are kinetic,potiental, electrical,wind heat light and chemical.Potiental energy is the same as stored energy. The stored energy is held within the gravitational field. If you lift an object and then throw the object when it is in the air it has kinetic. Which is the complete oppisite of potiental. The faster you (or an object moves) the more kinetic energy. If you are on a rollar coaster and you are stopped than you have potiental when you are moving than you have kinetic energy.
